Philips LL553T 4x2.5+2x1.5 Gen2 WH LED-lichtband en lichtbalk

The Philips LL553T is a high-performance LED light band and light bar system engineered for professional indoor lighting applications. Delivering an impressive 20,000 lumens with a system efficacy of 148 lm/W, it combines exceptional brightness with energy efficiency. The neutral white 4000 K colour temperature and CRI >80 ensure accurate colour rendering, making it ideal for offices, retail spaces, and educational facilities. Its robust steel housing in white (WH) and IP20 rating suit clean indoor environments. The integrated DALI-compatible driver enables seamless integration into lighting control systems for dynamic dimming and energy management. Through-wiring with 4x2.5mm² + 2x1.5mm² conductors simplifies installation in continuous row configurations. With a long service life of 50,000 hours (L70B50) and wide operating temperature range (-20 to +35 °C), the LL553T is a reliable, future-proof lighting solution.
